一类具有局部化非线性反应项的扩散方程组解的爆破性质(英文)
Blowup Properties for a Diffusion System with Localized Nonlinear Reactions
【摘要】 作者讨论了一类具有局部化非线性反应项的扩散方程组解的全局存在性与有限时刻爆破问题.在合适的条件下,作者得到了同时爆破和爆破集,并建立了爆破估计.
【Abstract】 The authors study the global existence and finite time blowup of nonnegative solutions of a diffusion system with localized reactions and homogeneous Dirichlet boundary.Under appropriate hypothesis,they also get the simultaneous blowup and establish the precise blowup estimates.
